T0 @ZZ whom it nfl/ay concern:

Be it known that I, DAVID E. LINDSAY, a citizen of the United States of America, residing at Etna, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Rails and 'Ties for Railroads, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in rails and ties for railroads; and the invention hasfor its primary obj ect to provide interlocking rails of a novel construction which will dispense with fishbars, fish-plates, and base-plates.

Another object of this invention is to provide a novel form of tie upon which my improved rails are mounted, the ties being constructed to prevent the rails from sliding or spreading, at the Same time forming a firm foundation for the rails.

A further object of this invention is to provide rails having practically a continuous tread, whereby the jarring of the rolling-stock passing over the rails will be reduced to a minimum.

A Still further object of this invention is to provide rails which can be laid and properly positioned upon their ties or supports by unskilled labor, the simple construction employed in connection with the rails permitting of the same being manufactured at a comparatively small cost.

With the above and other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts, to be hereinafter more fully described and claimed, and, referring to the drawings accompanying this application, like numerals of reference designate corresponding parts throughout both views, in which- Figure 1 is a perspective view of one of my improved rails, showing the same supported by ties or sleepers. Fig. 2 is a cross-sectional view of the same.

To put my invention into practice, I construct iny improved rails of two parts 1 and 2, the part 1 consisting of a head 3, a web portion 4, and a base-fiange 5, while the part 2 consists of a web portion 6 and a baSe-fiange 7. When the parts 1 and 2 are secured to'- gether, a rail is provided having substantially the same configuration in cross-section as the ordinary type of rail at present used.

The base-flanges 5 and 7 of the parts 1 and 2 are provided with depending flanges 8, having beveled surfaces 9 9, which form a dovetail groove 10 when the parts 1 and 2 are secured together.

In constructing the parts 1 and 2 of my improved rails I form the same of equal length; but in placing them together they are arranged alternately, whereby the central portion 11 of the part 2 will coincide with the web portions 4 of the confronting ends of the parts 1 1, while the confronting ends of the parts 2 2 will coincide with the central portion of the parts 1. In this manner the adjoining ends of the parts 1 and 2 will be braced, and to secure the parts together I use bolts and nuts 12, which pass through the confronting endsof the parts 1 1 and the central portion 11 of the part 2. kLikewise the confronting ends of the parts 2 2 will be secured to the central portions of the parts 1 1.

In conjunction with my improved rail I use ties or sleepers 14, which are preferably constructed of metal. The upper faces of the ties or sleepers are provided with transverse dovetail tongues 15, adapted to engage in the dovetail grooves 10, formed by the base-fianges 5 and 7 of my improved rail. The ties or sleepers 14 are arranged whereby the tongues 15 will longitudinally aline with one another to support the parts 1 and 2 of p my improved rail, said parts being locked in engagement with the tongues 15 ofthe ties or sleepers 14 by the bolts and nuts 12 12.

The parts of my improved rails can be easily rolled, and the manner in which Said parts are secured together dispenses with the use of fish bars or plates, while the tongues 15 of the ties or sleepers dispense with base-plates.

I do not care to confine myself to the weight of rail or the dimensions thereof, and such changes in the construction of the rail as are permissible by the appended claims may be resorted to without departing froml the spirit and scope of the invention.

What I claim, and desire to secure by Letters Patent, is

1. The combination with ties having dovetail tongues, of a rail adapted to engage the tongues of said ties, said rail consisting of two parts, a head carried by one of said parts and common to both parts, a base-iiange car'- ried by each part and forming a dov etail groove when said parts are secured together, substantially as described.

2. The combination with ties having dove- IOO IIO

tail tongues, oi a rail engaged by said tongues, said rail consisting of two parts ali ternately arranged together, base-anges carried by said parts and forming a dovetail groove to receive the tongues of said ties, substantially as described.

3. The combination with ties having tongues, of a rail adapted to engage said tongues, said rail consisting of two parts, the s ends of one part being arranged centrally of the other part, base-flanges carried by said parts and engaging said tongues, means to secure said parts together, substantially as described.

4. A tie provided on its upper face with a tongue having inclined side edges, combined with a rail having base-anges resting on said tongue, and depending side flanges carried by said base-flanges, said depending side flanges having inclined inner faces engaging the inclined side edges of said tongue.

5. A rail formed in two members adapted l to be secured together, each member vhaving a base-flange provided with a groove, and a tie having a tongue adapted to t in said grooves in the base-anges of the rail memers.

6. A rail provided in its base with a groove, combined with a tie, and means carried by the tie engaging in the groove of the rail and securing the rail to the tie.

7. A two-part rail provided in its base with a groove, combined with a tie, and means carried by the tie engaging in the groove of the rail and securing said rail to the tie.

8. A rail provided with a base, and depending side ianges carried by said base, combined with a tie, and means locking the tie to said side flanges of the rail.

In testimony whereof I affix my signature in the presence of two witnesses.

DAVID E. LINDSAY.
